The software Tonelib JAM is an alternative to Rocksmith and is on sale right now (50% off). You can load psarc-files (CLDCs) into the software and have the notes charted as tab, notes or 3D synced to the backing track. Software can also be used for FREE even after the 30 day trial you can still use the software. You just have to wait 15s until you can use the software (similar to Reaper after the trial period).

Not the user you replied to, but I found ToneLib Jam to be what I wanted. You can try it indefinitely but it has an annoying window that pops up when you start it telling you to buy it. I waited until they had a sale and got it 50% off. Source: over 1 year ago

Note detection is bad on RS, active instruments make this worse, tone controls need to be zeroed out. RS is horrid for learning music, id suggest you download Tone-LIB Jam for free and use it to learn songs. Audio exclusivity is required by the Wise audio in RS btw. Source: over 1 year ago

Rakarrack has a GUI written in FLTK. It was my earliest adventure with guitar effects and DSP (ca 2008); it ran on a potato laptop and still kept up, which made the whole setup actually viable for spontaneous jam sessions at other people's places. Good times. - Source: Hacker News / 4 months ago

I was messing around with a guitar, a USB interface, and a software called https://rakarrack.sourceforge.net/ (I don't know if it is available on windows) and it was a lot of fun! You could scroll through the presets and make the guitar sound like all kinds of things! Definitely worth tinkering with. Source: 12 months ago
